omprising of an inner bowl, an outer bowl and an insulated server, the extra space on the bowl rim of this casserole helps easy placing and removal. The doubled walled insulation is achieved by nesting the two bowls of different sizes together, thus creating an air gap between the walls. The cover too, is double walled. Maximum heat is retained when the server is full. This casserole in fact provides you with two bowls to serve both hot and cold food.
